The point is, nobody with more than 1 bitcoin prefer to leave 24 words on a piece of paper.
So I will launch a challenge! I will sell 10 CryptoPlatz Vault with the seed recovery phrase of 1 Bitcoin, encrypted with CryptoPlatz App.
The first man that decrypt the seed recovery phrase can take 1 Bitcoin for him.
First you said that cryptoplatz is well suited to back up software wallets whose seed has already been exposed to an online device anyway (fair point, as I said).
But now you claim that
actually, people will want to use cryptoplatz when they have 1BTC or more in a wallet, since paper is not good enough?
I personally don't believe anyone should store roughly $20,000 USD (at the time of writing) in a software wallet (except maybe exchanges since they need it for their operation).
This means the two statements appear as contradictory.
Most people should want to store +1BTC on a wallet that has been created on either an airgapped, offline PC or
mayyybe on an airgapped hardware wallets; in both cases, the seed never left the device except being shown on screen, allowing the user to write it down on paper.
Do keep in mind that they can easily do 10 copies of said paper and laminate them (waterproofing), to store in various locations. All offline, all without any security concerns.
Why would such users want to now
enter their very secure seed in a phone app?
Sorry if I'm being harsh, but the concept makes no sense to me.
Creating a seed phrase on a smart card? Maybe. Using a smart card to store a seed phrase that had been securely created on a different hardware device and requires typing it into an app? That makes really no sense.
